Meetings generally occur on the the first and third Thursdays of the month, between 6:30pm and 9pm as well as the fourth Saturday of the month from 2pm to 6pm. Meetings are scheduled through the SGVTech Meetup Group. Check there for up to date information.
These are hands-on working meetings. There are tables, free wifi, and a group of knowledgeable people. So come, bring your projects, show off your new toys, and just connect with your fellow hardware geeks. There is even a projector if you want to do a mini-presentation.
